More than 350 organizations, including leading U.S. medical, advocacy and professional organizations, have sent a letter to President Trump expressing their “unequivocal support for the safety of vaccines.”

The effort, organized by the American Academy of Pediatrics, reflects the growing alarm among a wide array of groups over Trump’s embrace of discredited claims about vaccine safety. After a meeting in January with Robert F. Kennedy Jr., a proponent of the debunked theory that vaccines cause autism, a Trump spokeswoman said he was considering creation of a commission on autism.

The myth that vaccines like the one that prevents measles are connected to autism has persisted despite rock-solid proof to the contrary. Donald Trump has given credence to such views in tweets and during a Republican debate, but as president he has said nothing to support vaccination opponents, so there is reason to hope that his views are changing.

As a scientist leading global efforts to develop vaccines for neglected poverty-related diseases like schistosomiasis and Chagas’ disease, and as the dad of an adult daughter with autism and other disabilities, I’m worried that our nation’s health will soon be threatened because we have not stood up to the pseudoscience and fake conspiracy claims of this movement.
